IINHALER [FOR MENTHOL OR SIMILAR SUBSTANCES.

SPECIFICATION formingpart of Letters Patent No. 672,322, dated April 16, 1901.

Application filed October 21, 1899. Serial No. 734,316. (No model.)

To a/ZZ whom, it may concern.-

Be it known that I, THEODOR HERRMANN GELLHAUS, a subject of the King of Prussia, Emperor of Germany, residing at Bant, near Wilhelmshafen, Prussia, Germany, have invented certain new and useful Improvements in Inhalers for Volatile Menthol or other Similar Substances, (for which I have applied for a patent in Germany, dated March 23, 1899,) of which the following is a specification.

This invention relates to an inhaler that is designed to facilitate the inhalation of volatile menthol and similar substances.

The apparatus is constructed and arranged as described below, with reference to the accompanying drawings, in which- Figure 1 is a vertical section of the apparatus, and Fig. 2 a section on the line a Z).

The apparatus consists, essentially, of four parts: first, of an exterior cup d, to which a straight tube is connected; secondly, of an interior cup 0, to which a curved tube is connected; thirdly, of a plug 6, arranged inside the interior cup, and, fourthly, of a piece of menthol f, arranged in the said plug c.

First. The exterior cup 01 is of a tulip or bell-like form, and to the middle of the bottom of the samea tube (1, of small diameter, is secured in any suitable manner. The inside of this cup is ground somewhat conically and serves for the reception of the cup 0.

Second. The interior cup 0 has likewise a tulip or bell-like form. As this interior cup 0 is inserted into the exterior cup d with the mouth downward, the closed end of the cup is accordingly at the top. To this closed end a tube 0, having a curved form, is connected by any suitable means, as in the case of the exterior cup. The outside of theinteriorcup c is ground conically to fit in the exterior cup 01 and produce an air-tight joint. The inside of the interior cup is likewise conical in form to receive the plug e.

Third. The plug 6 fits in the interior cup c in a similar manner as the interior cup 0 fits in the exterior cup 61. It has the form of a common glass stopper, but is hollowed out almost to the bottom, so as to hold the piece of menthol. For the purpose of securing the menthol in the stopper two projections g are provided diametrically opposite to each other.

The bottom of the plug 6 is provided with a number of small perforations e for the passage of air.

Fourth. The piece of menthol f, that is cylindrical in form, is provided with two large and several small longitudinal grooves h" and, further, with a transverse groove h at about the middle. The two large grooves are diametrically opposite to each other, and these, together with the transverse groove h and the projections g, secure the menthol in the manner of a bayonet-joint, Whereas the smaller grooves allow the passage of air.

Owing to the curved form of the one tube the mouth thereof can be brought into the immediate proximity of the back of the throat. On sucking at this tube air will enter at 00, pass through the plug c along the grooves in the menthol, where it will become charged with the volatized menthol, and, finally, pass I through the curved tube into the immediate proximity of the back of the throat, which it will accordingly meet. By reversing the apparatus it can be used for the nose. The stopper can be used for headache by removing it from the cup.

What I claim, and desire to secure by Letters Patent of the United States, is

1. An inhaler for volatile solid substances consisting of two tulip or bell-like hollow bodies 0 and (Z that can be inserted into each other, of which the one 0 so receives a piece of such substance, held in a plug, and provided with grooves on its circumference, that the air inhaled through the apparatus must pass over the volatile solid substances, and the latter can be removed from the receiver at any time to be used for local application.

2. In an inhaler for volatile solid substances, the combination of a bell-like hollow casing d provided with a straight tube (1, a bell-like casing 0 let into said casing d, said casing 0 being provided with a curved tube 0, and a plug 6 let into the said. casing c, said plug c being provided with the perforations e and the recess c aud a piece of solid volatile substance inserted in said recess 6 and provided with grooves, substantially as set forth.

3. In an inhaler for volatile solid substances, the combination of a bell-like hollow casing (1 provided with a straight tube l adapted to engage over the projections g of d, a bell-like casing a let into said casing d, the plug eand the small longitudinal grooves said casing 0 being provided with a curved 'i, substantially as described and for the purtube a, a plug 6 let into the said casing c, pose specified.
